Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and more specifically, to a multi-degree-of-freedom adaptive cutting tool structure for cutting irregular shapes using powder high-speed steel. Background Technology

[0002] High-speed steel is a high-performance tool steel containing a high proportion of alloying elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. It is renowned for its extremely high hardness, wear resistance, and red hardness, and is commonly used in the manufacture of cutting tools (drills, end mills, turning tools), molds, and wear-resistant parts. Powder metallurgy is an advanced method for manufacturing high-speed steel. Compared to traditional cast high-speed steel, powder-coated high-speed steel has a more uniform and finer carbide distribution, less segregation, and higher purity. This results in superior overall performance: higher hardness, better toughness, stronger wear resistance and red hardness, and better grindability and heat treatment stability.

[0003] Currently, the cutting tools used for high-speed steel cutting are usually standard-shaped tools, such as flat end mills and ball end mills. However, these milling cutters are not easy to adjust the cutting surface, and the waste chips produced by cutting are also easy to spread and scratch the workpiece. Utility Model Content

[0005] This utility model provides the following technical solution: a multi-degree-of-freedom adaptive tool structure for cutting irregular shapes of powder high-speed steel, including a reinforcing shaft, on which a cutting component is provided; The cutting assembly includes a cutter head disposed on the top of a reinforcing shaft. The outer side of the cutter head is provided with a plurality of guide grooves, and a first blade for cutting is provided on one side of the inner wall of each guide groove. Each first blade is provided with a limiting plate. A diversion groove is provided on the inner wall of the plurality of guide grooves, and each diversion groove is located on one side of the corresponding first blade. A second blade is fixedly disposed on the outer side of the plurality of limiting plates, and a limiting rod is provided in the middle of each limiting plate. As can be seen, in the above technical solution, the first blade cuts the workpiece when it rotates, and the waste generated during cutting can be gathered by the first blade and then discharged through the first blade. The way of gathering the waste by the first blade can effectively prevent the waste generated during cutting from spreading and prevent the waste from scratching the workpiece. Optionally, in a possible implementation, one end of the limiting rod extends to the first blade and is threadedly connected to the first blade, and the outer side of the second blade extends to the outer side of the first blade. A heat dissipation slot is provided on one side of the surface of the plurality of guide grooves, and each heat dissipation slot is located on the outer side of the cutter head. The cross-sectional shape of the second blade is set to a polygon, and the limiting plate is rotatably connected to the first blade.

The limiting plate supports the second blade and the limiting rod positions the limiting plate, which effectively ensures the stability of the second blade during cutting. Furthermore, different cutting requirements can be achieved by adjusting the angle of the second blade.

[0006] The technical effects and advantages of this utility model are as follows: By setting up the cutting components and using the corresponding cooperation of each structure, the waste generated during cutting can be gathered by the first blade and then discharged through the first blade. The method of gathering the waste by the first blade can effectively prevent the spread of the waste generated during cutting and prevent the waste from scratching the workpiece.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] As attached Figures 1-4 The multi-degree-of-freedom adaptive tool structure for cutting irregular shapes of powder high-speed steel, as shown, uses a cutting component set on the reinforcing shaft 1. The waste generated during cutting can be gathered by the first blade 4 and then discharged through the first blade 4. The method of gathering the waste by the first blade 4 can effectively prevent the spread of waste generated during cutting and prevent the waste from scratching the workpiece. In addition, during cutting, a limiting plate 6 and a second blade 7 can be installed on the first blade 4 according to the requirements through a limiting rod 8. The limiting plate 6 supports the second blade 7 and the limiting rod 8 positions the limiting plate 6, effectively ensuring the stability of the second blade 7 during cutting. Different cutting requirements can also be achieved by adjusting the angle of the second blade 7. The specific structural settings of the component are as follows. The cutting assembly includes a cutter head 2 set on the top of the reinforcing shaft 1. Several guide grooves 3 are opened on the outer side of the cutter head 2. A first blade 4 for cutting is set on one side of the inner wall of each guide groove 3. A limiting plate 6 is set on each first blade 4. A diversion groove 5 is opened on the inner wall of the multiple guide grooves 3. Each diversion groove 5 is located on one side of the corresponding first blade 4. A second blade 7 is fixedly set on the outer side of the multiple limiting plates 6. A limiting rod 8 is set in the middle of each limiting plate 6. One end of the limiting rod 8 extends to the first blade 4 and is threadedly connected to the first blade 4. The outer side of the second blade 7 extends to the outer side of the first blade 4. A heat dissipation slot 9 is provided on one side of the surface of multiple guide chute 3. Each heat dissipation slot 9 is located on the outer side of the cutter head 2. The cross-sectional shape of the second blade 7 is set as a polygon. The limiting disk 6 is rotatably connected to the first blade 4.

[0015] The specific working principle is as follows: During cutting, the tool is installed on the cutting equipment. The cutting equipment drives the reinforcing shaft 1 and the tool head 2 to drive each first blade 4 to rotate. When the first blade 4 rotates, it cuts the workpiece. The waste generated during cutting can be gathered by the first blade 4 and then discharged through the first blade 4. The way the waste is gathered by the first blade 4 can effectively prevent the waste generated during cutting from spreading and prevent the waste from scratching the workpiece. Furthermore, during cutting, a limiting plate 6 and a second blade 7 can be installed on the first blade 4 via a limiting rod 8 as needed. The limiting plate 6 supports the second blade 7, and the limiting rod 8 positions the limiting plate 6, effectively ensuring the stability of the second blade 7 during cutting. Different cutting requirements can also be achieved by adjusting the angle of the second blade 7.

[0016] Unlike existing technologies, this application discloses a multi-degree-of-freedom adaptive tool structure for cutting irregular shapes using powder high-speed steel. During cutting, the waste chips generated are gathered by the first blade 4 and then discharged through the first blade 4. This gathering of waste chips by the first blade 4 effectively prevents the diffusion of waste chips and avoids scratching the workpiece. Furthermore, during cutting, a limiting plate 6 and a second blade 7 can be installed on the first blade 4 via a limiting rod 8 as needed. The limiting plate 6 supports the second blade 7, and the limiting rod 8 positions the limiting plate 6, effectively ensuring the stability of the second blade 7 during cutting. Different cutting requirements can also be met by adjusting the angle of the second blade 7.

[0017] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
